Problems solved by technology

[0004] However, the extension distance of the first type of technology is limited, and the transmission distance of 10Mbps can be extended to 300 meters
The second type of technology has a very low transmission rate and cannot meet the requirements of high-speed transmission
The third type of technology is complex to implement, the equipment is bulky, requires an external power supply, and is inconvenient to install

Embodiment Construction

[0039] In the prior art, the transmission distance is limited due to the decrease of the frequency characteristic of the twisted pair, but as long as the data communication speed is reduced, it can also ensure that the receiving party receives normal harmonics. The present invention utilizes an extender to distribute the data of the single-channel twisted pair to two groups of communication channels of the dual-channel twisted pair, and another extender combines the data of the two groups of communication channels of the dual-channel twisted pair to the single channel twisted pair. In this way, by reducing the speed of data transmission, the transmission distance of data can be greatly improved.

[0040] see figure 1 The present invention provides a device for extending the transmission distance of twisted pair in Ethernet, which includes two extenders connected to network equipment via single-channel twisted pair and dual-channel twisted pair with two sets of communication c...

Abstract

The invention provides a device, an extender and a method for extending the transmission distance of a twisted pair in an Ethernet, including two extenders respectively connected to network equipment via a single-channel twisted pair and a dual-channel twisted pair with two sets of communication channels , the two extenders are located at both ends of the dual-channel twisted pair, one extender is used to distribute the received data of the single-channel twisted pair to two groups of communication channels of the dual-channel twisted pair, and the other An extender is used to merge the data of the two communication channels of the dual-channel twisted pair into the single-channel twisted pair. It can meet the requirements of high-speed transmission, and is simple to implement, small in size and easy to install.

Description

technical field [0001] The invention relates to the technical field of Ethernet transmission, in particular to a device, an extender and a method for extending the transmission distance of a twisted pair in the Ethernet. Background technique [0002] In the field of Ethernet transmission, twisted pair is widely used in the construction of local area networks in various fields such as industrial control, video surveillance, and voice transmission because of its strong anti-interference ability, long transmission distance, easy wiring, and low price. However, due to the large attenuation of the signal by the twisted pair itself, it can only be limited within 100 meters when performing high-speed signal transmission. Taking the currently commonly used Category 5 line as an example, its effective transmission distance in 10BAST-T and 100BASE-T networks is up to 100 meters, which causes unnecessary troubles for network construction and is not conducive to performance improvement....
